The tanks of Barur and Penukondapuram, Salem district, were 

 stocked with E. Suratensis a species which is non-indigenous to 

 these tanks. 



6. Collair scheme. — This work is at present being held up owing to 

 the existence of stake nets and basket cruives, the removal of which 

 is absolutely necessary for working out the scheme successfully and it 

 will be taken up later. 



7. Ippur fish farm. — This is still under construction and from the 

 recent report I had from the Executive Engineer, Nellore, the farm 

 will not be ready for another three months. All the heavy fishery 

 utensils were, however, removed to the farm and kept in the store 

 room and some of the ponds have also been planted with lilies. The 

 farm will, it is hoped, be brought into working order before the 

 close of the current financial year. 



8. Acclimatisation of tinea vulgaris. — As stated in paragraph 3 

 supra, the small consignment of these fish which was introduced 

 into the Sunkesula fish farm in February 191 4, was again supple- 

 mented by a further consignment during the year under report. The 

 result will be reported in due course, 



9. Foivder factory scheme. —The ponds in the late gunpowder factory 

 at Vyasarpady were handed over to this department on application 

 from us, to utilize them for piscicultural purposes. My scheme to 

 use these most valuable ponds for growing larvicides and other 

 valuable fish was sanctioned by Government in G.O. Mis. No. 1854, 

 Revenue, dated 9th /August 19 15. The several ponds were cleaned 

 and provided with suitable shutters, screens, etc., and stocked with 

 the following fish, viz., Etroptus suratensis, Megalops cyprinoides 

 and a large number of larvicidal fish. E. Suratensis are being kept 

 specially for introducing into many of the permanent water tanks 

 — vide my letter Ref. No, 167, dated i6th June 191 6. where they are 

 at present non-indigenous. These fish which are highly prized by the 

 Indian population, will be bred on a large scale at our farms for 

 stocking districts where they are at present non-indigenous. 



One of the ponds is set aside for O. olfax (gourami) as a resting 

 place (after their long journey) for the consignments which we hope 

 to get (since obtained) from Java and Mauritius. These will be 

 distributed to the fish farms where careful selections will be made for 

 breeding purposes. The flesh value of these fish is exceedingly great 

 and they should eventually prove a most valuable addition to the food 

 supply of the country. They are non-predaceous and live mostly on 

 pond weed and lilies. 



10. Nallamalais scheme. — As per my report,; dated the 15th Sep- 

 tember 1915, approved by the Surgeon-General and sanctioned by 

 Government in their Order No. 2689, Revenue, dated 3rd December 

 1915, this scheme is to try and improve the notorious fever zone in 

 the Nallamalais, Kurnool district, by the use of fish larvicides. 

 Arrangements are being made for breeding these fish in large numbers 

 in the hills at a site chosen as near as possible to the scene of opera- 

 tions, for the purpose of stocking all the isolated permanent water- 

 holes existing in these jungles. During the dry weather the above 

 mentioned holes form the only possible mosquito-breeding and
